MoSi2 Heating Element has the ability to withstand oxidation at high temperatures. This is due to the formation of a thin and adhesive protective layer of quartz glass (SiO2) on the surface. When the element temperature over 1700ºC, SiO2 protective layer which melting point is 1710ºC was fused, and because of the surface tension, it fused into drops, which is useless. However, when element continue working in oxidizing atmospheres, the SiO2 protective layer is spontaneously rebuilt.

Notice: It is no good to use Molybdenum Disilicide Heating Element for Long-term within a range of 400-700ºC, otherwise the element will be powdered by the strong low temperature oxidation.
